ISO 52000-1:2017建立了一个系统、全面和模块化的结构，用于以整体方式评估新建筑和现有建筑（EPB）的能源性能。 它适用于通过测量或计算评估建筑物的总体能源使用，以及根据一次能源或其他能源相关指标计算能源性能。它考虑了不同应用的具体可能性和局限性，例如建筑设计、“竣工”的新建筑、使用阶段的现有建筑以及翻修。 注:引言中的表1显示了ISO 52000-1:2017在ISO 52000-1:2017规定的模块化结构背景下，在EPB标准集内的相对位置。

ISO 52000-1:2017 establishes a systematic, comprehensive and modular structure for assessing the energy performance of new and existing buildings (EPB) in a holistic way. It is applicable to the assessment of overall energy use of a building, by measurement or calculation, and the calculation of energy performance in terms of primary energy or other energy-related metrics. It takes into account the specific possibilities and limitations for the different applications, such as building design, new buildings 'as built', and existing buildings in the use phase as well as renovation. NOTE Table 1 in the Introduction shows the relative position of ISO 52000-1:2017 within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1:2017.
